APYRATUS FOR BOOKKEEPING.

*c Application led January 15. 1924.

To (1U 'to/Loot it may conccwr:

Re it known that l. CARL MrcunnsnN. a citizen of Germany,.residing at. Rostock, in the State of Mecklenburg. Germany, have invented certain new and useful Improvements in Apparatus for Bookkeeping: and I do hereby declare the following to be a full, clear, and exact'description of the invention. such as vvill enable others skilled in the art to which it appertains, to make and use the same..

My invention relates to improvements in the method of"and apparatus Jfor bookkeeping, and the object of the improvements-` is to provide a. method ensuring the correctentry ot' commercial transactions by simultaneously making' an original and a copy of the registrations on the day-book and the individual accounts by means of a type- Writing machine. `With this object in yview l make ay continuous record on an original entry sheet representing the day-hook' and individual records on sheets of papen' cards or the like representing the account` books, said individual sheets oi' paper or cards being placed on or below the original entry sheet together with carbon paper tor making' a ,carbon copy. ln order that the items eptered on the individual account sheets he simultaneously entered in the correct columns ot' the original sheet or day-book the original sheet. and the account sheets are shi''tahle relatively to each other, and means are provided ior insuring the correct relative positions ot the lines and columns oi the sheets. Furthermore means are provided whereby neu' sheets placed on the original sheet or dayluook are brought into the correct positions relatively to the original sheet, so that the items are entered on the original sheet at the correct places.

.In my in'iproved system special notes` communications. and the like may he made u'hcn entcringitems on the original sheet and the sheets receiving the accounts, designed to he mailed to other parties or firms for informing the same ot the regisl'ration's` regarding the same, which informations are automatically printed when Writ` ing on the day-book and account sheets, tor which purpose the account sheets or cards are equipped with sheets placed below the .same so that copies oi' the record are made thereon by .neans ot" carbon paper.

Yn car 'ving out the method l make use ting machine provided with a Serial No. 886.434.

plane platen or writing' plate. The nia-- chine is equipped \vith\stationary printingr mechanism and a carriagwe movable. in the direction ot the lines and carrying a plane platen which is movable transversely ot' the lines 'for printing on the sheets or cards placed thereon. An important. feature ol my improved typewriting'f machine is that 1t permits visible writing. Other features of the improved machin. adapting the same to my improved method of book-keepingr ivillcappear fromI the following description.

In\--order that my invention be clearly understood my improved typewriting ma` chine has been shown in the accompanying drawings, in which the same reference characters have been used in all the views to indicate corresponding parts. In said dra\vings,-

Figs, and 3, show a sect-ion taken ou the line lll-lIl of Fig. 1, and

Fig. i, is a plan view of the horizontal platen or writing plate showingr the means tor adjusting the sheets of paper or cards thereon.

ln my improved method ot bookkeeping by means ot' a` typewritng machine entries are simultanemisly made on an original entry sheet representing for example a dayhook, and on exchangeable sheets or cards adapted to be combined into account hooks. rl`he original sheet and the account sheets are simultaneoushv printed by means ot' arhon paper, the account. sheets" being' placed on or-helow the original sheet.. The entries are made in the. correct columns, and the items are automatically summarized, so that after each entry the totals may be printed on the original sheet as Well as on the account sheet o1" sheets. 1n some cases the account sheets are provided with additional sheets adapted to be' printed simultaneously therewith by une-ans of carbon paper or in any other suitable way, which may he used for example for sending' Ycommunications, statcmentsof account., and thef like to the custcmer.

The aforesaid and other con'nnercial transactions lare written by means of a typewriting` machine provided with novel means adapting 'the same to the"ohject aimed In the example shown in the figures my improved typewriting machine comprises Slo lll)

Gn the freine carriage C is guided which carries the pieten, sind it provides :t support i'or the levers, key lever mechanism for operating the 'type levers, and the line und ietter spacing mechanisms, )erts of which are mounted on the trarne A. At the rear end of the frame A nprights E are mounted, which provide a support for mechanical operating mechanism D, end which support e suosidiary freine F on which the ribbon spoois G, the type segment H and the mechanism for operating the ribbon feeding mechanism and the type levers are mounted.

At the front side of the niechine and at the rear of the key board l a guide reii l is mounted on the frame A, and :it the rear side of the machine and in front of the uprights E n. similar guide rail 2 is mounted on the frame A, which rails extend over the whole breadth of the machine. To the rail 2 a spring barrel 3 is secured the spring of l which is connected'by a bund 4 with, the

carriage C for shifting the seme in the direction of the line. The carriage is supported on the guide rails l and 2 through the intermediary of rollers 5t and it shows rails 6 providing a guide Ior e writing plete or platen i supported thereon through rollers '7. The seid pieten is in the forni of e plone plete mede from i suitable materiel such rubber. t shows two pins 9 adepte ed to tif; the origina?h sheet l() on the platen.

The account sheets or the like i8 are printed simultaneously With the original sheet, for which purpose they are placed on the original sheet together with sheets of carbon peper, and they ere adapted to be shifted relativeiy to the originel sheetVV in the direction of the lines and in the direction of the columns, according to the entries to loe mede thereon.

'lfhe ietter specinfi; mechanism is constructed follows:

To the iiottoin side is secured which is T23 wheel 28 secured'to s pair of brackets To the shaft secured in which teeth corresponds to tir 'the letters, The step-b v-step nvenient of the ratchet wheel ill by the pull o the spring barrel 3 is controlled by pawls Z'l/ and Pi; mounted on a rockeror level wethe pawl l being;` movable on the said lever cireumferentialluv of the ratchet wheel 3l, while the pawl 32) is tixed thereto. The lever :il is connected by a link 35 with a spring pres .l arm 37 seeinfed to a shaft and the shalt carries arms 3S having a universal bar if secured thereto, which bar bears on key levers 4t). Therefore7 when depressingl a key the universal bar 39 is moved upwardly, and the movable pawl 32 is brought out of engagement with the teeth of the ratchet wheel 251, while. the fixed pawl 25J-l is brought into engagement therewith,

Therefore the pawl Si? is advanced one .step corresponding' to the pitch of the ratchet, wheel 3l. When rele; Iing` the depressed ke),v 'the members 5l to :2S are returned into initial positions by the spring' ll, so that the pawl 33 releases the wheel 3l and permits the saine to be advanced one step according to the advanced po ition of the pawl I laine spacing is elfected by shifting the platen 8. The ke) board shows two line spacing keyY levers all which are. secured to a. rock shaft 42 mounted in suitable bearings provided on the fame Al. At their free ends the said levers carrjY a bar 43 which extends over the whole breadth of the carriage (3. To the bottom side of the platen 8 and substantially to the middle thereof a rack at is secured the teeth of 'which have a pitch equal to the space of the lines. The said rack is engaged by a shifting paw] t5 and a locking pawl Lt6. T he pawl l0 is roekingly mounted at 48 and it is acted upon by a spring 47 holding the same in engagement with the rack ai. accii'iental n'iovement o'l the platen 8 towards the key-limard. rl`he pawl t5 is jointed to a rocker :t9 suiniorted at nl and it is acted upon by a spring ai' holdingl the same in ei' {cmen' f'l'h the rack 4s. To the rocker jointed which is connected Ar .5:2 liavingi` a rocking support at rThe rod .'31 is acted upon by a spring u connected to the-earriage C at 55.

There- Q." the rocker if) and the pawl Yl5 are shifted one step towards the keiv board7 and the 'ngf {35?- is pnt onder tension. .'ifter reihe kegv l the spring' :Tril advances the one step and the pawl -lo is held ii elevated position by a shoe 56. lt it is ed to move the platen 8 by hand, the ever 52 is rocked by the ke)Y lever 4.1 bevond 'the position shown in dotted lines. Thereby e rod 5l pulled forwardly, and an arm 30 made integral with the rocker 49 and The pawl prevents havinga nose 50 is rocked dmvnwardljl' and the drawings a plurality ol' calculating' n'iechanisn'is K are provided in my machine, which mechanisms are niounted'on the carriage so as to correspond to the individual eohnnns of the original sheet. Each calculating,l apparatus is equipped at bottom part with a gear wheel 5'? adapted, according to the posit-ion of the carriage C, to mesh with an elongated gear wheel 58 of an v operating mechanism L. The length oi' the operating mechanism L is such that it can be connected by a connecting rod 19 with any of the digit key levers showing the figures from l to 9 land the zero sign, Therefore, when depressing any of the digit keys the operating machanism L is actuated accord ingly, and they movement imparted'thereto transmitted through the gear wheels 58. and 57 to the calculating mechanism.

The key levers are arranged in a 'manner known in the art, and at each side of the ke)7 board-there is a kevv 4l for line spacing. The bar N operates the letter spacing mechanis-m 27 to 39. The key board comprises two shift keys for writing small letters and capitals and special signs. The operation ot' the shift keys will be described hereinafter.

The operation of the type levers Gl b v the keys of the key-board l appears from Fig. l. Each kegy is secured to a ke)y lever 40 supported at a5 and aeted upon by a spring L10 and jointed at its rear .end to a vertical rod (52. The top end of the said rod jointed to a lever (3S- having,l its fulcrum at Gel' and connected by a link 65 with a type lever Gl mounted at G6. When depressing a keyv the lever o?, is rocked upwardly into the position shown in dotted lines so asV to throw the type lever Gl forwardly and downwardly1 and against the platen as is indicated b v the arrows (3T. Elastic operation is ensured b v springs Hb',

The vertical rods (SQ are connected at their bottom ends to links (l) adapted to Operate the type levers b v mechanical means. As appears from Fig. 3. a motor D is mounted on a bracket TO secured to the upright, E, and the rotaryv movement of the motor is transmitted through a suitable gearing 7l to a cam shaft T2. B v setting` one of the links GS) into position tor operation by the cam shaft the rod 62 is lifted and the type thrown upwardly.
